Titanium dioxide (TiO2) is used as a white pigment for architecture, cosmetic, and paint because it efficiently scatters visible light, there by imparting whiteness, brightness and opacity. This work describes a means of improving the whiteness and reflectivity of ceramic coated TiO2 pigment. To retain and enhance the properties of white pigment, we adopted core-shell system with the silica (SiO2), aluminum oxide (Al2O3) and zirconium dioxide (ZrO2) as shell materials. These inorganic surface treatments provide improvements in important performance properties such as dispersibility in water and in a range of organic liquids, hiding power efficiency, chalk resistance, and resistance to discoloration by photo-reduction. Control of the shell thickness and whiteness of the TiO2 pigment was important factor for high quality outdoor white pigments and their shell thickness was achieved by regulating the reaction time, concentration and shell materials. Details of the coloration and phase structure of TiO2 pigment were characterized by UV-vis, CIE Lab color parameter measurements, TEM (transmission electron microscopy) and XRD (powder X-ray diffraction).
